🧠 About IQ Spark

IQ Spark is a free browser-based pattern reasoning test and educational content site focused on intelligence testing. Our goal is to help readers understand what pattern reasoning tasks can show, what they cannot show, and how formal assessments differ from quick online tools.

We keep the experience free, simple, and privacy-conscious. Results are calculated locally in the browser, and the site is designed for curiosity, self-exploration, and general education rather than diagnosis or placement.

The tasks on IQ Spark focus on non-verbal pattern reasoning. That makes the site useful for exploring visual logic, rule detection, and abstract problem solving.

The format is inspired by classic matrix-style reasoning tests, including literature around Raven's Progressive Matrices, but IQ Spark is not a licensed administration of Raven, WAIS, Stanford-Binet, or any other formal commercial assessment.

For a full explanation of question format, score interpretation, and known limits, see our methodology page.

The score shown on IQ Spark is an educational IQ-style estimate mapped to a reference scale. It is meant to give readers a familiar frame for interpreting performance, not to serve as an official psychometric report.

Performance can change with fatigue, stress, distractions, screen size, time pressure, and prior exposure to similar questions. For decisions involving school services, diagnosis, workplace accommodations, or clinical care, a supervised assessment by a qualified professional is still necessary.

IQ Spark content is written and maintained by the IQ Spark editorial team. We prioritize test publisher manuals, government health and education resources, and well-established overview literature when explaining intelligence testing concepts.

We do not present site articles as clinical advice, and we avoid naming individual reviewers or experts unless we can transparently identify and verify that contribution. Our standards, correction process, and source guidelines are listed in our editorial policy.

• Raven, J., Raven, J. C., & Court, J. H. Manual for Raven's Progressive Matrices and Vocabulary Scales.
• Wechsler, D. WAIS-IV Technical and Interpretive Manual.
• Roid, G. H. Stanford-Binet Intelligence Scales, Fifth Edition, Technical Manual.
• Government and public-interest resources used in relevant articles are described in our editorial workflow.

If you notice an error, an outdated statement, or wording that overstates what the tool can do, please contact us at iqsparktest@gmail.com. We review correction requests and update pages when clarification is needed.
